The muscle that lets your eye blink is the fastest muscle in your body. It enables you to blink 5 times a second. On standard you blink 15 000 times a day. That’s about 10 times per minute, or more than five million times a year. Women blink more than men. Jean-Dominique Bauby, a French writer suffering from “locked-in” syndrome, wrote the manuscript “The Driving Bell and the Butterfly” by blinking his left eyelid – the only part of his body that could move.
